Thought this would be of interest.
Was out on the weekend on a short Moose hunt. Crunched the numbers for fuel consumption based off hours of run time and actual fuel used.
I was very surprised at how low my numbers were. Boat is a 20' Wooldridge Sport with a 5.7 carb and 212 pump.
I averaged 7.5 GPH for the whole trip. Pretty reasonable I thought.
